    摘要: PROBLEM TO BE SOLVED: To provide a valve-type pressure regulator in which a ball is brought in contact with an opening peripheral portion of a small-diameter flow passage so as to stabilize product performance by reliably seating the ball on the opening peripheral portion.
    SOLUTION: The pressure regulator 1 includes a housing 2 having a small-diameter flow passage 6 with an inflow port 9 and also having a large-diameter flow passage 5 with an outflow port 12. The small-diameter flow passage 6 and the large-diameter flow passage 5 are interconnected in the housing 2. An opening 8 of the small-diameter flow passage 6 is formed in the connection part between the small-diameter flow passage 6 and the large-diameter flow passage 5 so as to face the large-diameter flow passage 5. The ball 3 in contact with the peripheral edge 11 of the opening 8 is disposed in the large-diameter flow passage 5. The ball 3 is pressed against the peripheral edge 11 by a valve spring 4. The inner diameter D1 of the large-diameter flow passage 5 is set such that the center gravity G of the ball 3 is closer to the center of the opening 8 than the peripheral edge 11 with the ball 3 in contact with the inner peripheral wall 5a of the large-diameter flow passage.

    摘要: PROBLEM TO BE SOLVED: To provide a check valve for a fuel pump having a ball made of ceramics as a valve element, capable of inhibiting cracks of the ball even when valve closing pressure is set high, and excellent in durability.
    SOLUTION: A seat portion for the ball 2 in a seat surface 13 formed in a check valve main body 1 is constructed to be an annular surface 13b having a curvature larger than the curvature of the ball 2 so that the ball 2 contacts with the annular surface 13b in a band-like area S. Stress acting on the ball 2 is made small even at high valve closing pressure and occurrence of cracks of the ball 2 is inhibited.

    摘要: PROBLEM TO BE SOLVED: To prevent the vibration of a check valve to be inserted into piping of a refrigerating cycle.
    SOLUTION: The check valve 100 to be inserted into the piping 5 of the refrigerating cycle comprises a valve seat 110, a spherical valve element 120, and a valve supporting member 130 integrated with the valve element. The rod valve supporting member 130 is slidably inserted into a guide member 140. A coil spring 150 energizes the valve supporting member 130 and the valve element 120 in a direction horizontal to a flowing direction F
    1 of refrigerant. A vibration absorbing spring 160 elastically supports the valve supporting member 130 at its outer periphery for absorbing vibration in a direction perpendicular to the flowing direction F
    1 of the refrigerant.
